I owned the 7D for a short time, and the 5D II. In the situation you describe I would take the 5D II every time. The 7D only if I wanted to shoot some action shots, sporting events or wildlife.


For noise and ISO the 5D II handles it better than the 7D.


With the 7D you could consider it a low light camera because you have a pop up flash and it is "available light". That wasn't a serious statement.


So I would say 5D II given the description you gave.
